摘要

Recently, a so called orthogonal spatial multiplexing (OSM) scheme was presented which allows simple maximum likelihood decoding at the receiver with single phase feedback. In this paper, by serially concatenating this scheme by a linear precoder, a new closed-loop SM scheme is proposed for two transmit and two receive antennas. By computer simulation results, we show that the proposed scheme outperforms the conventional SM and OSM.
